I am building a new computer and am not sure how many watts I'll need.
It will be a nforce4 ultra board, athlon 64 3500, two sata HD's in a raid array, an x800xl video card, one burner and one regular dvd drive, with 1gb dual channel ram and maybe a sound card if the onboard sucks. Any suggestions? Thanks!

hmmm, 480+ watt no less.

Antec or PC power and cooling are good.

You could actually get away with a quality 350w PSU, but I would recommend looking at 420w minimum. Focus on sticking with a name-brand.

Can you guys explain why the name brand is so important? El Cheapo is $30 and Antec, for example, is three of four times as much! What is the big difference?

Well "El Cheapo" PSU's are poorly made (small capacitors, etc) and won't hold their rated voltages under heavy load. And sometimes under heavy load, they just crap out, taking out itself and sometimes, the rest of your rig. Most of the time, these cheap PSU's are rated at their peak wattages, not the sustained wattage. For example, the El Cheapo 500w PSU may have a peak power of 500w, but it sustains maybe say 350w. However, a quality PSU such as the PC Power and Cooling 510 has a sustained wattage of 510w, with peak wattages around 700w. El Cheapo PSU's also have weaker rails.

Generic power supplies mislead on the advertised specs, are found wanting on the rails, and are not likely to deliever clean, efficient power. They entice you by adverstising, for example, 550w and charging $30. What you're seeing listed is the peak power (as opposed to sustained) under the best possible conditions. As temperatures rise, the sustained wattage decreases. When you see a generic 550w, you're seeing this peak wattage at unrealistically low temps. In other words, it's marketing.

For a modern system such as you're building, it's highly advisable not to skimp on the PSU. By going generic, you won't be getting the wattage/specs you thought you paid for. If you're dealing with a tight budget, a quality 350w is preferable to a generic 500w+.

I would recomend always getting a little more than you need so that you have room to upgrade. And always make sure you are buying from a quality manufacturer such as Antec,OCZ,Ernemax,Pc Power and Cooler etc...
